What to Do When a Mercedes-Benz C200 Fails to Start After Power Loss?

If the battery has been disconnected or is low on power, pull the switch upward until the side window is completely closed, and hold the switch in this position for 1 second. Hold the switch in the closing direction until the roller blind is fully closed, then continue holding the switch for another 1 second, and then hold the switch in the opening direction. Hold the switch in the opening direction again until the sunroof opens another 10 centimeters, then release the switch and hold it in the closing direction.
I had just bought a Mercedes-Benz C200 when I ran into the annoying problem of the car not starting after a power outage. That day, there was a heavy rainstorm causing a power failure and restoration. When I went to drive, pressing the button gave no response at all, making me jump with anxiety. Later, after some research, I found out it might be due to the battery being completely drained or the electronic anti-theft system being locked. I first tried using a power bank connected to the cigarette lighter port to charge it for a while, but it didn’t help much. Then, I unplugged and replugged the key a few times to reset the anti-theft system, but it still didn’t work. A friend suggested calling a nearby repair shop or Mercedes-Benz 4S店 for towing service. They brought professional tools for testing and discovered that the battery was too old to hold a charge. Now, I regularly check the battery’s health and have even installed a voltage stabilizer at home to prevent power outages from affecting the car. This experience reminded me that even new cars need attention to electrical maintenance.
